Title: Oxalis crassipes identification
Answered by: Joe Marcus

QUESTION:

I'm trying to identify a plant that has appeared in several containers on my balcony. The largest plant is about a foot tall, with triangular leaves, small white flowers with yellow centers, and has just grown green berries. I'm not sure if I should pull it up or fertilize it. Thank you so much for your help.

ANSWER:

Sometimes we can identify a plant from a description; often we cannot. The only plant that comes to mind for us is the South American native White wood sorrell, Oxalis crassipes. It is a common greenhouse and container weed. This species also has a pink-flowered form. If this is not the plant in your container, a picture or set of pictures will help. Here's how to send them to us:

1. Tell us where and when you found the plant and describe the site where it occurred.

2. Take several images including details of leaves, stems, flowers, fruit, and the overall plant.

3. Save images in JPEG format, with resolution set at 300 pixels per inch.

4. Send email with images attached to id@smartyplants.org. Put Plant Identification Request in the subject line of your email.
